PERNUTATION-PADLOCK.

SPECIFICAION forming part of Letters Patent No. 398,660, dated February 26, 1889.

Application lerl June 13, 1888.

.To alti m1710111. 'mf/1J concern Be it known that we, GEORGE F. SEISER, CALvIN R. JOHNSON, and MORGAN B. PERRY,

citizens of the United States, residing at Fort 5 Roya-l, in the county ot Henry and State of Kentucky, have invented new and useful Iml lock, and to provide simple and improved i r and rotates on the said annular plate, and is means for cha nging the combinations.

The invention consists in a certain novel -construction and arrangement ot parts for service, fully set forth hereinafter in connection with the accompanying drawings, where- Figure l is a side view of a padlock embodyingI our improvements. Fig. 2 is a longitudinal central sectional view of the same, showing the parts arranged in the unlocked position. Fig. 3 is a detail perspective view of the arbor, the cap-plate, and the tumblers. Fig. al. is a like view of one oi the tumbler@ Fig. 5 is alike view of one of the springs. Fig. 6 is a like view of the dial having the numbers or characters of the combination thereon. Fig. 7 is a transverse sectional view of the case on the line fr: ol' Fig. l.

Serial No. 276,927. (Model) is tapered, so that the studs or projections cS on this leg are tapered, whereas the corresponding studs or proj eetions on the otherleg are segmental in shape.

The spindle or arborD is mounted in a bearing, l), in the cap-plate, and the removable tip D on the upper end of the spindle or arbor is tapered,and is mounted in a socket, d,

in the upper end of the case between the openings a u, and on the exposed or outer end ot the spindle or arbor is arranged the head or knob F.

An annular bearing-plate, F, is arranged on the outer side ol the cap-plate, and is provided with aperturesffto receive studsf on the cap-plate.

G represents the dial carrying the numbers or characters ot the combination, which bea-rs provided with a shoulder, g, which lits within the plate. 'lheshouldere ol' thehead orkncb which bears on the dial is provided with a small pin, c', which is adapted to engage one of the sockets g, which are arranged in an annular series around the arbor or spindle. rl`he sockets in this series are numbered or provided with other suitable distinguishingeharacters, and when the pin e is engaged in one oi" these sockets the dial rotates with the head or knob. The cap-plate is provided with a suitable indienting-mark. with which to align the characters on the dial.

H designates a rigid tumbler, which is mounted on the arbor or spindleneartheeapplate, and a spring, l, is coiled on the arbor or l spindle between the cap-plate and the said Referring` to the drawings, A designates the inclosing shell or ease of the improved lock,

which is provided at one end with the openings ct a, and the opposite end of the same is left open for the reception of the cap-plate B, which may be secured rigidly in place in any preferred manner.

The legs c of the staple C are provided with the shoulders c to prevent them from beingI introduced too far into the case through the openings d d, and they are i'urther provided on their inner sides with notches cF ci?, that correspond in number with the tuml'ilers employed. The inner side of one of the legs c on the tumblers immediately below and hold 9 the latter properly spaced on the arbor. The tumblers are further provided near their peripheries with the depending annular iiange lr', and in the grooves or channels 7:2, which are th us formed by the flan ges and the sleeves,

IOS

are arranged the pins Z. The upper sides of the rigid and removable tumblers, with the exception of that at the upper end of the arbor or spindle, are provided with similar pins, Z, to travel in the grooves or channels k2 and engage the pins on the lower sides of the tumblers immediately above. At diametricallyopposite points in the peripheries of the tumblers are formed the notches M M', the former of which are curved or segmental, while the latter are V-shaped. notches M are respectively aligned, and the legs ot' the staple may then be passed into the case through the openings a a and inserted until the shoulders on the Vlegs bear against the outer side of the case. It will be evident that when .the arbor is rotated the Vrigid tumbler is similarly actuated, and the engagingpins-on the removable tumblers enable th-e latter to be turned in thc same way, so that their notches may be aligned. It will be observed that the 'notches M are designed to receivethe leg of the staple having the segmental studs or projections, and the notches M are designed to receive the legs having V- shapcd studs or projections.

N N represent springs, of a number correspending to the tumblers, and they `consist of the loops yn, adapted to receive the leg of the staple, and the curved arms n ya', integral with the loops and embracing the annular iianges of the tumblers. The loops are received in a longitudinal depression or groove,`

O, Ain the side of the shell or case, (being thus prevented trom turning with the tumblers,) and the arms bear tightlyagainst the o pposite sides of the said flanges, and thus hold the tumblers in any desired position.

Various means have heretofore been employed t'o secure the sprin in place and prevent them from turning with the tumblers; but the above construction, which consists in providing the springs with loops which engage the above-mentioned depression or groove O, obviates the necessity of supplemental securing devices.

The operation of the lock is as Follows: It will be understood that the upper tumbler (or that near the upper or free end oi` the arbor) must be adjusted iirst, owing to the fact that all the tumblers must be turned in order to turn the upper one. Then the next lower tumbler is adj usted, and so on, the rigid tumbler being the last one to be adjusted. In order to turn the upper t-umbler, it will be understood that the arbor must be rotated until the pins on the upper sides of the tumblers have engaged the corresponding sides of the lower pins on the adjacent tumblers, 'and all the tumblers are therefore rotated in the same direction. Having thus arranged the tumblers, the arbor is rotated until the first character ot' the combination is aligned with the indicating-mark on the cap-plate, (thus adj usting the upper tumbler.) Then the arbor is turned in the reverse direction a number of times equal to the tumblers which are unset The notches M and the j (namely, three in the lock shown'in the drawings) in to cause the second tumbler to rotate, and then the second character ot the combination is aligned withv the indicating-mark, (thus adjusting the second tumbler.) Then the arbor is turned in the reverse direction .a number of times equal to the unset tumblers, (namely, two,) and the third character of the combination is aligned with the indicatingmark, (thus adjusting the third tunibler,) and so on until all the loose tumliilers are set, after which the rigid tumbler is adjusted without disturbing the loose tumblers and by aligning the last. character of the combination with the'indicating-mark. of the tumblers are now all aligned, and the V -shaped notches are also aligned, so that the studs or projections on the inner sides of the legs of the staple are disengaged, and the staple may be removed.

The springs will Vhold the tumblers lirmly in place until 'the staple is replaced,when the arbor may be turned a number of times to throw the notches o'l the tumblers outof alignment with the legs ol' the staple, and the lock is adjusted.

To change the combination, thestaljile removed, (the combination cannot be changed while the staple is locked in place,) the head or handle on the arbor is drawn out against the force of the spring l, and the pin e is engaged .in a different socket, thus changing all the numbers or characters of the combination. The combination is thus changed without removing any ot the parts oi? the lock or opening the case .or shell of the same, and may be The segmental notches TOO changed as often as the lock is unlocked. The

combination cannot be changed while the staple is in the lock, for the reason that in order to detach the pin c from the socket ofthe dial it is necessary to draw the arbor or spindle outward. This also draws the tumblers toward the lower end of the case, and it their edges are engaged in the notches in the legs of the staple they cannot be moved. The legs of the staple cannot be drawn down, owing to the shoulders above mentioned, which bear on the upper end ot' the case around the openings a a.

Having thus described the invention, what we claim, and desire to secure by Letters Patent of the United States, is-

. l. In a permutation-padlock, the case having' a suitable longitudinal depression or groove,
